Agreed! IMO, that particular Feature Request is critical and would resolve concerns about having an application so tightly bound to a JCR repository. I notice it says resolved. Perhaps it will be in the next GateIn release? Thanks Patrice!
I'm still interested in knowing what all is stored in the JCR.
You could use Crash http://code.google.com/p/crsh/ , which provides u a terminal-based client to browse within JCR repository.
WEBDAV access is also useful
